1 . A high school teacher and his students have discovered that an asteroid (小行星) hit by a NASA spacecraft, in a test run for saving the Earth from an impact, is behaving unexpectedly. The find could have effects on future planetary defense missions.
The Double Asteroid Redirection Test (DART) is a project designed to launch and crash a fridge-sized spacecraft into an asteroid called Dimorphos, orbiting a larger asteroid Didymos. The purpose of the exercise was to see how significantly the previous path of Dimorphos could be changed by the impact. Before DART’s impact, it would take Dimorphos 11 hours and 55 minutes to complete a lap around Didymos. NASA was hoping the DART crash could change the cycle by about 73 seconds, but observations made in the weeks following the impact determined that the results were much more significant, reducing Dimorphos’ orbital period by some 33 minutes.
But California high school teacher Jonathan Swift and his students discovered that Dimorphos’ orbital period was a full minute longer than the time reported by NASA last year. They used the school’s observatory to track Dimorphos and Didymos for several months last fall. Swift presented his class’ findings at the American Astronomical Society conference in June. The DART team has since confirmed that Dimorphos did indeed continue slowing in its orbit up to a month after the impact.
Scientists aren’t sure exactly what is behind the slowdown of Dimorphos. But recent observations of the asteroid have revealed a vast field of large rocks were kicked up by the impact. It’s possible that some of the larger space rocks fell back onto Dimorphos within that first month, slowing its orbit further, DART team member Harrison Agrusa said.
The DART team plans to release its own report on the unexpected findings in the coming weeks. However, complete answers may have to wait until 2026, when the European Space Ageney’s Hera spacecraft is scheduled to investigate the crash site up closely.

It is a hot sunny Saturday morning on the farm. Maya, Duksie and Doobie are helping Mama K in her vegetable garden. The children work all morning.
Mama K always gives the children a treat for helping her. Sometimes it’s cake or chocolate; sometimes it’s apples, pears or oranges. Mama K has only one rule. “Share it fair!” The children know they must share the treats equally, so they all get the same amount.
Today Mama K has baked a round strawberry cake with pink icing (糖霜) and berries from her garden. The children wait on the grass for their treat. “Here you go!” smiles Mama K. “But remember the rule. Share it fair!”
Maya has the first turn to share the cake. She uses the knife to draw lines in the icing. The others watch her. She does not cut the cake yet. The others must first agree if her way is fair. “I think I will make two cuts down like this. Now we have three slices, all the same!” Maya shows them. There is one line on the left and the other on the right.
“No way!” says Duksie. “The one in the middle is much too big!” Doobie also shakes his head. Maya laughs and tells Duksie to try.
“Pass me the knife.I’ll do it,” says Duksie First she rubs out Maya’s pattern in the icing, and then she makes one cut across and one down. “Look, I have made my three slices!” “That’s not fair!” shout Maya and Doobie together,.
“Why don’t you try, Doobie?” says Duksie. “I bet you can’t do it!”
“I wish the cake was a square, and then it would be easy!” says Doobie thoughtfully. And then! A picture comes into Doobie’s head. He sees the silver badge (标识) at the front of his father’s big red Benz truck. “I’ve got it! I’ve got it! I know how to do it,” shouts Doobie.
“How did you work it out?” Maya asks. Doobie smiles to himself. For now it’s his secret. Later, he will tell his dad.

If you look at the dynamic “Global Temperatures” map on NASA’s website, you can see the historic temperature change over time across the planet as the timeline goes from 1880 to the modern day. By 2019, the entire planet is in red, orange, and yellow colors, indicating temperatures much higher than the historical average in every country and human inhabitance.
If the timeline went to 2023, the map would look even worse. That’s because the summer of 2023 was the hottest ever, according to ocean monitors. July was the hottest month in recorded history. Next July could be worse. Unless we do something quickly, we face dealing with more and more dangerous and expensive natural disasters in the future.
Forest fires sent smoke from Canada across the North American continent, causing New York City to have the worst air quality in its recorded history. Heavy rainstorms fell on Vermont and the Northeastern United States in just a couple of days in the middle of July, which exceeded the amount that area would usually receive in two months and caused extreme damage to homes and businesses. Around the same time, flash flooding in Bucks County, Pennsylvania — north of Philadelphia — killed nearly a dozen people.
Erich Fischer, a researcher specializing in climate studies at the Swiss Federal Institute of Technology, is concerned that natural disasters could get much worse in the future—and in ways we cannot predict. He called for a “strike for climate justice,” which actually took place on Sept. 15, 2023. “The strategy needs to be twofold (双重的) . We need to decrease carbon emissions as much as realistically possible. That is already happening with people using electric cars and other green technologies. At the same time, we also need to find ways to predict the risk of natural disasters ahead of time,” said Erich Fischer.

5 . Phonetic (语音) information—the smallest sound elements of speech - is considered by researchers to be the basis of language. Babies are thought to learn these small sound elements and add them together to make words. But a new study suggests that phonetic information is learnt too late and slowly for this to be the case. Instead, rhythmic (有韵律的) speech helps babies learn language and is effective even in the first few months of life.
Researchers from the Trinity College Dublin investigated babies’ ability to process phonetic information during their first year. Their study, published in the journal Nature Communications. found that phonetic information wasn’t successfully encoded (编码) until seven months old, and did not occur very often at 11 months old when babies began to say their first words. From then individual speech sounds are still added in very slowly—too slowly to form the basis of language.
The researchers recorded patterns of brain activity in 50 babies at four, seven, and eleven months old as they watched a video of a primary school teacher singing 18 nursery rhymes (童谣) to a baby. They found that phonetic encoding in babies appeared inchmeal over the first year of life, beginning with labial sounds (e.g. “d” for “daddy”) and nasal sounds (e.g. “m” for “mummy”), with the “read out” progressively looking more like that of adults.
“The reason why we use nursery rhymes is because that is the best way for babies to discover and connect sounds with language, so we are teaching them how to speak,” said Giovanni Di Liberto, lead author of the study at Trinity College Dublin in Ireland. “Parents should talk and sing to their babies as much as possible or use baby-directed speech because it will make a difference to language outcome,” she added.

Ten miles away stood a house with shiny red walls, a green garden and an apple tree. A young girl’s face would be seen reflecting from one of the large glassy windows. Her name is Maggie. Her eyes were sparkling and on her face there was a smile which could light a million candles. She seemed to be longing for a chance to play like a young child, but she had no strength in her legs because she and her family met with an accident, in which she lost both her legs.
But her spirit was strong. She would be inspired by seeing birds fly. The flying eagle would make her want to fly. She was lonely. She longed for a true friend who would talk to her and teach her to fly or at least tell her stories about soaring into the blue sky.
One evening, Maggie slowly rolled her wheelchair to the giant window and looked out to the many houses that lay across the road. Suddenly she heard someone singing and then could see an old man in a pilot suit singing in glory. The beautiful sound and the melody made the little girl happy. Suddenly he stopped and gazed up toward her. “What are you staring at?” he said angrily. “You think I’m a circus clown? (马戏团小丑)” “No, Sir. I was just listening to you. You sing very well,” she said. “I don’t need your praises. I don’t need anyone!” he shouted. He started to walk to his house and shut the door. Tears rolled down from her apple-red cheeks as the man shouted at her. She was lonely.
Next morning, Maggie pushed her wheelchair across the garden to the stone road as little children played hide-and-seek around her. Suddenly out of nowhere a loading truck came rumbling across toward her. Terrified, she tried to move away from its path but the wheels of her chair were stuck. “Oh my,” she thought as the truck came in her direction fast, with the driver unaware of the obstruction in front of him. She screamed loudly but in a split second she was pulled out of her wheelchair by someone and fell on the ground. She closed her eyes and shivered as the truck passed her whistling. As she opened her eyes, she could see a man standing beside her.

Mozart struggled during his teens and early twenties. Though already a productive composer, he had to work as an organist (风琴手)to make ends meet.
Underpaid by his frustratingly average work, he felt a

What, then, is holding you back? Rich Karlgaard, author of Late Bloomers, argues that our culture’s obsession with early achievement discourages us from pursuing our passions.
As a result, most of us end up choosing professional excellence over personal fulfillment and often we lose ourselves in the process.
The authors of Dark Horse, Todd Rose and Ogi Ogas of Harvard’s School of Education, noticed the negative effects of early specialization in a study of people who came out of nowhere to achieve great success. “Despite feeling

For many, an act of kindness is its own reward. But Eva Hachey found her selflessness answered in ways she could never have imagined.
For weeks, Eva Hachey had imagined adopting a golden Chihuahua with a white spot on its forehead. And there he was, at her local SPCA in Fredericton, New Brunswick. The dog had been abused by his previous owners and was timid. “He’d come to me, then back away and growl, then come back to me,” Hachey said. “After 15 minutes, the attendant picked him up and put him in my lap. He started giving me kisses. He stole my heart in that moment.” She adopted the ten-month-old puppy on the spot and named him Bruno.
Bruno lived happily with Hachey and her 35-year-old daughter, Angel Hutchinson, for five months. Then, on the evening of September 26, 2016, Hachey, 52 at the time, returned home as usual at 8 p. m. from her job as a chiropractic assistant and office manager. And as usual, she ate supper in front of the TV in the living room. Around 10:30, a friend called, just as Bruno went into Hutchinson’s room to go to sleep for the night. Hachey and her friend chatted a bit, and as Hachey hung up, she noticed the time was 11:08.
“The next thing I remember was a male voice saying, ‘Eva, Eva, wake up.’ It was an emergency doctor,” said Hachey. “I looked around, and the room was just full of people. And I said, ‘What are you doing in my house?’”
What they were doing was saving her life. By the time Hachey had hung up with her friend, Hutchinson was fast asleep in her bedroom and Bruno was in his usual spot next to her under the blankets. Hachey believed Bruno heard something odd then and possibly went to the living room to investigate.

___________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________I’m good at making excuses. I came up with a new one every time the idea of returning to college presented itself. I had enrolled in a university at 21 but later quit. As the years passed, I regretted not finishing my English degree. But I always comforted myself with excuses — I have three little ones who need me at home. I’m busy with the children’s school activities. I can’t go back to school at 50. Old dogs can’t learn new tricks.
The truth was that I was just plain scared to go back to school. What if I needed remedial (补习的) courses? What if a professor called attention to me? What if I walked into a classroom and there was nowhere to sit? What if I stood out in a sea of young faces?
After my children finished college, they insisted it was my turn, so I called Dalton State College and set up a time to take the Compass Test to see if I needed remedial courses. The next day, when I was on the highway heading there, Rachel, my middle child called. When she learned my destination, I heard the pride in her voice. “You’ve got this, Mama!”
That was all it took. Hot tears tumbled down my cheeks as she spoke words of encouragement to me. It turned out that I scored high on the English test but would need to take two remedial courses for the math section. But I didn’t care. After decades of excuses, I’d finally thrown my leg over the high fence of fear. I couldn’t wait to register for classes.
My first course was U. S. History. I’ve never been good with dates, but the professor calmed my nerves. “I don’t care about dates, but I expect you to know the names of significant individuals. For instance, who was the first person to set foot on the moon?”
“Neil Armstrong,” chorused several students.
“Does anyone know when that event took place?”
My heart leapt at the question, because I was celebrating my fifteenth birthday on that day!
